Which of the following is NOT a responsibility of the President regarding national security?

• A. Declares war
• B. Commander-in-Chief
• C. Chief diplomat/negotiates treaties
• D. Directs foreign policy and national security apparatus (via NSC)

Answer: (A)

Presidents shape national security by directing foreign policy, serving as Commander-in-Chief, and handling diplomacy, including negotiating treaties. The President commands the armed forces, sets strategic priorities, and chairs or oversees the national security apparatus like the National Security Council. The diplomatic role includes negotiating treaties, though those treaties require Senate confirmation, which is a built-in check on that power. The power to declare war, however, is held by Congress in the Constitution. The President can request action or engage military force under frameworks like the War Powers Resolution, but cannot unilaterally declare war. That combination makes declaring war the action that is not a presidential responsibility.
